“…The lack of a stable friction film combined with the observed micro ploughing effect seems to be the reason for the high wear rates compared to pad material B. However, higher wear rates compared to the measured wear rates of the C/C brake pads (Pad C) for C/SiC – C/C friction pairings can be found in the literature 12,13 …”

“…Compared with C/C-SiC metal brake pads, brake pads with metal elements have been shown to have a lower wear rate, making them more suitable for driving below the initial braking speed <49 km/h. 137 Also, based on the research of semi-metallic brake pads, it was concluded that the hardness of the material and the porosity of the material have a significant impact on the wear of the material. 138 So, as the porosity and hardness of the brake pads increase, so does the wear.…”

The braking system is one of the important systems from the aspect of vehicle safety, but it is also one of the systems that has a significant impact on the environment. Brakes are considered to be a source of non-exhaust particles, that is sources that create particles by the wear of the elements that are in contact with each other, and in this case, the brake friction elements (brake pads and rotating disc). Such particles often contain heavy metals that are part of the friction elements. There are a number of influencing factors that can affect the wear of the friction elements and increase the concentration of the formed particles. Laboratory methods of testing wear and particle formation, road tests and various simulations of brake wear are most often used for testing. In this paper, a review of methodologies for testing the formation of particles from the braking system, the materials used in the composition of the friction elements of the brake, as well as factors affecting the wear rate and concentration of particles of different sizes, based on the conclusions of other authors is presented. Based on this review, it can be concluded which quantities and factors need special attention during further research in the mechanism of formation of non-exhaust particles whose source is the vehicle braking system.

“…Unlike in carbon nanotubes and nanofibers, modification only improves the mechanical properties of braking composites. In addition, braking composites suffer from friction coefficient instabilities [ 11 , 12 , 13 ], which can cause their wear rate to increase. While numerous works have focused on the mechanical and frictional properties of graphene/polymer and graphene/metal composites [ 14 , 15 , 16 ], few studies describing C/C composites are available.…”

In this work, we developed an interface modified by graphene to simultaneously improve the mechanical and frictional properties of carbon/graphene/carbon (C/G/C) composite. Results indicated that the C/G/C composite exhibits remarkably improved interfacial bonding mode, static and dynamic mechanical performance, thermal conductivity, and frictional properties in comparison with those of the C/C composite. The weight contents of carbon fibers, graphene and pyrolytic carbon are 31.6, 0.3 and 68.1 wt %, respectively. The matrix of the C/G/C composite was mainly composed of rough laminar (RL) pyrocarbon. The average hardness by nanoindentation of the C/G/C and C/C composite matrices were 0.473 and 0.751 GPa, respectively. The flexural strength (three point bending), interlaminar shear strength (ILSS), interfacial debonding strength (IDS), internal friction and storage modulus of the C/C composite were 106, 10.3, 7.6, 0.038 and 12.7 GPa, respectively. Those properties of the C/G/C composite increased by 76.4%, 44.6%, 168.4% and 22.8%, respectively, and their internal friction decreased by 42.1% in comparison with those of the C/C composite. Owing to the lower hardness of the matrix, improved fiber/matrix interface bonding strength, and self-lubricating properties of graphene, a complete friction film was easily formed on the friction surface of the modified composite. Compared with the C/C composite, the C/G/C composite exhibited stable friction coefficients and lower wear losses at simulating air-plane normal landing (NL) and rejected take-off (RTO). The method appears to be a competitive approach to improve the mechanical and frictional properties of C/C composites simultaneously.
